Problems solved by technology

[0003] Each of these production processes has its own advantages and disadvantages. Although scribing drilling can solve the problem of single-piece production, its efficiency and accuracy are poor; making drilling mold drilling is suitable for small batch and multi-variety production, but the accuracy of drilling position is high. It is poor, and it is not suitable to ensure high position accuracy; the special machine tool for multi-axis headstock drilling is suitable for large-scale production of a single specification, and the production efficiency and drilling position accuracy are ideal, but the variety and specification cannot be changed, and it is not suitable for multi-variety and small-batch production
Especially when processing irregularly arranged holes in a single piece, the production...

Abstract

The invention provides a rotary table transmission device of a numerical control drilling machine, belonging to the field of mechanical technology. The device aims at solving the technical problems of poor location of a rotary table, low accuracy of drilling and the like of the existing numerical control drilling machine. The rotary table transmission device is arranged on a frame of the numerical control drilling machine and comprises the rotary table which is arranged on the frame and used for clamping disc workpieces and a motor for driving the rotary table to rotate, wherein a worm gear transmission mechanism used for driving the rotary table to rotate is arranged between the rotary table and the motor, and the frame is provided with a locating mechanism used for pressing a worm to preventing the rotary table from rotating when in drilling. The rotary table transmission device is wide in application scope, high in drilling accuracy, simple in structure, good in locating effect and stable in running.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a numerical control drilling machine, in particular to a rotary table transmission device of the numerical control drilling machine. Background technique [0002] At present, a drilling machine is a machine used for drilling, tapping and other processing of workpieces. At present, drilling machines have been widely used in the field of machinery, and there are generally three methods for processing the circumferential holes of disc parts. One is to draw lines and drill holes on the parts during single-piece production; Die drilling; the third is to make multi-axis headstock special machine tool drilling for large-volume and small-variety production. [0003] Each of these production processes has its own advantages and disadvantages. Although scribing drilling can solve the problem of single-piece production, its efficiency and accuracy are poor; making drilling mold drilling is...
